For the large part and for C code, I would say that the difference is
small in most cases for x86-64. I see a small lead in floating point
performance using the Studio compiler, and a small lead with integer
performance using GCC. However, either one might come out in the lead
for any given test case.
When it comes to SPARC code, the Studio compiler is clearly in the
